    The fan in the back of the tower is not running either. When I push the power button nothing happends. the pwer light is very dim. I tried replacing the power supply, no change. But, the button is pushed it use to click on, now it doesn't. When I plug it in I can hear a very low hum coming from the tower.

    I used the same power supply which was 350. I noticed that the power light is on but very dim, is that any indication of the motherboard having problems.

It sounds like there is something funny going on side the case since you replaced the power supply. First thing is to check for shorts. Blow out any dust inside the case and then try to reseat the memory and expansion cards.Also, be sure to ground yourself when touching the components.
If this doesn't work you can can pick up a SoYo Tech Aid card ( here ). It will show you whats actually going on while the computer is trying to POST and will help you narrow down the problem.

You need to replace your power supply or have a technician do it. You can get one for $25-30.

    So it's the fan in back of your tower, not your power supply fan? Is that correct? You can also replace those, but it's not that big a deal if that one is not running. I've seen several new computers that don't even come with those.

    What is the wattage of the new power supply compared to the old one?

    It should be something like 350W or 400W. Just make sure the new one is not LESS wattage than the previous.

    If that's fine, there could be a bad connection with the motherboard.

T5020 emachine seems to have dead power supply- how can I confirm?

If the PSU fans only work for a short time usually this means that the PSU is shot

If you suspect your power supply has gone bad, there are a few basic things you can do to test it. First, plug the computer in and try to start up the computer. If the computer can start up or shows signs of having power (the hard drives spin up, or the fans turn on) the power supply might be fine, and you may have an issue with your motherboard or RAM. If the computer won't start at all, open the case and then turn the power supply on and attempt to start the computer. Observe the motherboard to see if any lights turn. If no lights turn on and there is no sign that power is being supplied to any of your devices, there's a decent chance that the power supply has burned out. If your computer experiences periodic crashing, feel the case near the power supply to see if it is hotter than normal, and smell the air. If the case is much hotter than normal or you smell burning, your power supply might be overheating, and may be damaged. hope this helps

I am not hearing the fans on this computer and i notice it heats up very quickly

With the computer turned off unseat and reseat the fan connectors back to the motherboard. If the fans are still not turning on then try some other new fans. If new ones won't turn on then you know for sure at that point the motherboard is going bad because its not putting out a high enough voltage to turn the fans on.

Louder whirring noise when turning on computer

Usually on startup the fans work a little harder then slow down. On newer computers they still have noticable fan noise. Most of what ou hear while the machine is running after start up is the power supply fan. When it starts to go bad you'll hear it all the time.

Emachines 1900+ gets power to the monitor and computer but wont boot

There could be a number of causes. Do you hear any beeps when the computer starts up? Try seating all the chips in the motherboard. That means, apply pressure to each individual chip on the motherboard with your finger or thumb. The goal is to make sure each chip is securely attached to the board. Sometimes, heat or new h/w installs partially "pop" some of the chips out of the motherboard - causing the circuitry to be disconnected...

Emachines 1900+ gets power to the monitor and computer but wont boot

Buy a dianostics card, and find out if its the RAM, CPU, OR Motherboard. (sounds like a ram or CPU problem though) if you have more than one stick of ram in the system, take one out, and power it up, if still not response, to the other stick out, and put the stick you took out the first time, and put it back in.
